Weight loss interventions associated with improvements in several symptoms of PCOS: Study

Pairs of independent reviewers screened the studies and analyzed the impact of weight-intervention on metabolic markers, hormonal markers, gynecological markers and quality of life compared to offering no additional care, usual care (metformin, oral contraceptives, standard advice) or a lower-intensity weight loss intervention (advice for weight loss without support). Interventions included behavioral interventions (diet or physical activity), current or previously licensed weight loss pharmacotherapy (or those which share a class-effect), bariatric surgery, or combinations of such interventions.

The researchers also spoke with 36 women who have PCOS to better inform their selection of primary outcomes and presentation of findings. The researchers found that weight loss interventions were associated with greater reductions in glycemic control and hormonal markers including the free androgen index (FAI). These findings indicate that weight loss interventions may be an effective tool for PCOS management in applied clinical settings, and clinicians could use these results to counsel patients with PCOS on the improvements in PCOS markers after weight loss and direct them towards appropriate interventions.
